Complete Past-Tense Paradigm: Active, Passive, Affirmative and Negative

1. Four sets of past-tense forms

The opening discussion of verbs presents the past-tense paradigm in four combinations: active/passive and affirmative/negative.

Word / formMeaning / explanation
فَعَلَhe did; affirmative active past.
فُعِلَit was done; affirmative passive past.
مَا فَعَلَhe did not do it; negative active past.
مَا فُعِلَit was not done; negative passive past.

Active versus passive specifies the perspective on the action; affirmative versus negative specifies whether the event is asserted or denied. These are two separate distinctions, hence four combinations.

2. Why the past tense has fourteen forms

The complete past-tense conjugation has fourteen forms. They are divided as follows:

Word / formMeaning / explanation
Third person: 6three masculine and three feminine, describing someone spoken about.
Second person: 6three masculine and three feminine, addressing someone directly.
First person: 2singular and plural, describing the speaker.

Third and second persons distinguish singular, dual and plural for each gender. First-person forms do not separately mark gender: a man or woman can say فَعَلْتُ. The distribution is therefore 6 + 6 + 2 = 14.

3. Third-person masculine: affirmative active and passive

The three masculine third-person forms refer to one man, two men, or a group of men. The same number distinction appears in the corresponding passive forms.

FormActivePassive
Singularفَعَلَ: he did.فُعِلَ: he was acted upon.
Dualفَعَلَا: they two did.فُعِلَا: those two were acted upon.
Pluralفَعَلُوا: they did.فُعِلُوا: they were acted upon.

The final ـا marks the dual and ـوا marks this masculine plural. Active identifies the doer; passive expresses the action as experienced by its grammatical subject.

4. Third-person feminine: affirmative active and passive

Feminine third-person forms refer to one woman, two women or a group of women. Their suffixes show both gender and number.

TypeFirst formSecond form
Singularفَعَلَتْ: she did.فُعِلَتْ: she was acted upon.
Dualفَعَلَتَا: the two women did.فُعِلَتَا: they two were acted upon.
Pluralفَعَلْنَ: the women did.فُعِلْنَ: they were acted upon.

Here ـتْ marks feminine singular, ـتَا feminine dual, and ـنَ feminine plural. In particular, فَعَلْنَ is not the masculine plural فَعَلُوا.

5. Second-person masculine: affirmative active and passive

Masculine second-person forms address one man, two men or a group of men. They use different endings from the third-person forms.

TypeFirst formSecond form
Singularفَعَلْتَ: you (one male) did.فُعِلْتَ: you were acted upon.
Dualفَعَلْتُمَا: you two did.فُعِلْتُمَا: you two were acted upon.
Pluralفَعَلْتُمْ: you men did.فُعِلْتُمْ: you men were acted upon.

The endings ـتَ، ـتُمَا، ـتُمْ distinguish singular, dual and plural. The vowel pattern inside the stem changes with voice, but person and number stay constant.

6. Second-person feminine: affirmative active and passive

Feminine second-person forms directly address one woman, two women or a group of women. The singular and plural endings differ from masculine forms, whereas the dual form is shared.

TypeFirst formSecond form
Singularفَعَلْتِ: you (one female) did.فُعِلْتِ: you were acted upon.
Dualفَعَلْتُمَا: you two women did.فُعِلْتُمَا: you two were acted upon.
Pluralفَعَلْتُنَّ: you women did.فُعِلْتُنَّ: you women were acted upon.

ـتِ indicates singular feminine address and ـتُنَّ feminine plural address. فَعَلْتُمَا alone cannot identify gender, because both dual addressee forms are identical.

7. First-person affirmative forms

There are only two first-person past forms: singular and plural. They are not divided by the speaker's gender.
Singular — فَعَلْتُ: I did. | فُعِلْتُ: I was acted upon.
Plural — فَعَلْنَا: we did. | فُعِلْنَا: we were acted upon.
The ending ـتُ identifies the singular speaker, and ـنَا denotes the speaker together with others.
The difference between فَعَلْتُ ('I did') and فَعَلْتَ ('you did', masculine singular) is the final vowel. Accurate vocalization is therefore essential.

8. The passive past: the basic vowel pattern

The active past relates the action to the doer; the passive past reports the event without naming the agent. For a regular three-root-letter verb, the pattern فَعَلَ becomes فُعِلَ.
فَعَلَ → فُعِلَ
The first consonant takes ḍammah and the vowelled consonant before the final consonant takes kasrah; the final consonant retains its appropriate ending.
ضَرَبَ → ضُرِبَ — struck → was struck.
كَتَبَ → كُتِبَ — wrote → was written.
The root remains, but the grammatical voice changes. Weak verbs may require further specialized changes; these examples are regular patterns.

9. Passive formation in the source examples

The source demonstrates passive formation with regular three-root-letter and derived past forms. The relevant stem vowels change while the underlying morphological structure remains recognizable.

Word / formMeaning / explanation
ضَرَبَ → ضُرِبَstruck → was struck.
سَمِعَ → سُمِعَheard → was heard.
أَكْرَمَ → أُكْرِمَhonored → was honored.
اِجْتَنَبَ → اُجْتُنِبَavoided → was avoided.

In the last example, the derived stem includes additional letters. Adding a ḍammah only to the first letter is insufficient: the internal vowels must also change to produce the correct passive form.

10. What active and passive actually mean

ضَرَبَ زَيْدٌ عَمْرًا — Zayd struck ʿAmr.
ضُرِبَ عَمْرٌ — ʿAmr was struck.
The first sentence uses an active verb: Zayd performs the action and ʿAmr receives it. In the second, the verb is passive: the event is reported as affecting ʿAmr, without naming the striker.
Therefore ضُرِبَ cannot be translated simply as “he struck.” The changed vowels indicate a change in grammatical voice, not a new lexical root.

11. Negating the past with mā

The past is negated by placing مَا before an affirmative past-tense verb. The verb's form and its person/number markers remain unchanged; negation comes from the particle mā.

Word / formMeaning / explanation
فَعَلَ → مَا فَعَلَhe did → he did not do.
فُعِلَ → مَا فُعِلَit was done → it was not done.
فَعَلْنَا → مَا فَعَلْنَاwe did → we did not do.
فُعِلْنَا → مَا فُعِلْنَاwe were acted upon → we were not acted upon.

The particle does not turn active into passive or change first person into third person. It changes only the sentence's polarity.

12. Masculine third-person negative past

Place mā before each masculine third-person active or passive form. The person and number remain the same.

FormActivePassive
Singularمَا فَعَلَ: he did not.مَا فُعِلَ: he was not acted upon.
Dualمَا فَعَلَا: those two did not.مَا فُعِلَا: those two were not acted upon.
Pluralمَا فَعَلُوا: they did not.مَا فُعِلُوا: they were not acted upon.

The ending ـوا remains in both negative plural forms. The active-passive distinction comes from the stem vowels, not the number suffix.

13. Feminine third-person negative past

The negative feminine third-person forms keep the same feminine number endings as the affirmative forms. Mā is a separate particle.

TypeFirst formSecond form
Singularمَا فَعَلَتْ: she did not.مَا فُعِلَتْ: she was not acted upon.
Dualمَا فَعَلَتَا: the two women did not.مَا فُعِلَتَا: they two were not acted upon.
Pluralمَا فَعَلْنَ: the women did not.مَا فُعِلْنَ: they were not acted upon.

The endings ـتْ، ـتَا، ـنَ still distinguish the three feminine numbers, even after negation.

14. Masculine second-person negative past

The masculine second-person negative forms preserve their addressee endings. Adding mā denies the event; it does not change who is addressed.

TypeFirst formSecond form
Singularمَا فَعَلْتَ: you did not.مَا فُعِلْتَ: you were not acted upon.
Dualمَا فَعَلْتُمَا: you two did not.مَا فُعِلْتُمَا: you two were not acted upon.
Pluralمَا فَعَلْتُمْ: you men did not.مَا فُعِلْتُمْ: you men were not acted upon.

The difference between مَا فَعَلْتَ and مَا فَعَلْتُ is the final vowel: “you did not” versus “I did not.”

15. Feminine second-person negative past

The feminine second-person negative forms also place mā before the past verb. The endings continue to show number and gender.

TypeFirst formSecond form
Singularمَا فَعَلْتِ: you (female) did not.مَا فُعِلْتِ: you were not acted upon.
Dualمَا فَعَلْتُمَا: you two women did not.مَا فُعِلْتُمَا: you two were not acted upon.
Pluralمَا فَعَلْتُنَّ: you women did not.مَا فُعِلْتُنَّ: you women were not acted upon.

ـتِ and ـتُنَّ specifically signal feminine addressees. Dual ـتُمَا is identical for masculine and feminine.

16. First-person negative past forms

First-person negative forms are produced by adding mā before the corresponding affirmative past. Active and passive remain distinct.
Singular — مَا فَعَلْتُ: I did not. | مَا فُعِلْتُ: I was not acted upon.
Plural — مَا فَعَلْنَا: we did not. | مَا فُعِلْنَا: we were not acted upon.
مَا كَتَبْتُ — I did not write.
مَا ضُرِبْنَا — we were not struck.
The person/number ending is stable in both examples. Voice is distinguished by the stem vowels, not by the first-person plural suffix.

17. Third person versus second person

Different suffixes distinguish third person from second person and first person even within a single root.

Word / formMeaning / explanation
ضَرَبَhe struck.
ضَرَبْتَyou (male singular) struck.
ضَرَبَتْshe struck.
ضَرَبْتِyou (female singular) struck.
ضَرَبْتُI struck.

Note the positions of sukūn and the short vowels: ضَرَبَتْ has final tāʾ with sukūn, whereas ضَرَبْتَ has a vowelless bāʾ and a fatḥah on tāʾ. Similar letters do not make the same form.

18. Comparing the dual endings

Dual verbs cannot all be formed by simply appending alif in the same way. Third-person masculine, third-person feminine and second-person dual have distinct structures.

Word / formMeaning / explanation
فَعَلَاthe two men did; third-person masculine dual.
فَعَلَتَاthe two women did; third-person feminine dual.
فَعَلْتُمَاyou two did; second-person dual for either gender.

All convey “two,” but “those two” is not “you two.” The distinction remains in the passive forms فُعِلَا، فُعِلَتَا، فُعِلْتُمَا.

19. Ta, ti and tu: a decisive vowel contrast

In several past forms, the vowel on final tāʾ identifies the person and gender.

Word / formMeaning / explanation
فَعَلْتَyou (masculine singular) did.
فَعَلْتِyou (feminine singular) did.
فَعَلْتُI did.

The same endings remain in the passive past:

Word / formMeaning / explanation
فُعِلْتَyou (male) were acted upon.
فُعِلْتِyou (female) were acted upon.
فُعِلْتُI was acted upon.

The stem vowels express voice, while the ending on tāʾ still expresses person and gender.

20. Recognizing masculine and feminine plural

Arabic uses distinct plural forms even when an English translation merely says “they,” “you all,” or “we.”

Word / formMeaning / explanation
فَعَلُواthey (men) did; masculine third-person plural.
فَعَلْنَthey (women) did; feminine third-person plural.
فَعَلْتُمْyou men did; masculine second-person plural.
فَعَلْتُنَّyou women did; feminine second-person plural.
فَعَلْنَاwe did; first-person plural for either gender.

The endings ـوا، ـنَ، ـتُمْ، ـتُنَّ، ـنَا cannot be exchanged merely because every form refers to multiple people.

21. The same root through four functions

A single root remains recognizable through four grammatical combinations, while vowels and particles change its grammatical meaning.

Word / formMeaning / explanation
كَتَبَhe wrote; affirmative active.
كُتِبَit was written; affirmative passive.
مَا كَتَبَhe did not write; negative active.
مَا كُتِبَit was not written; negative passive.

All contain the root letters ك، ت، ب. Passive voice requires a different verbal vowel pattern; past negation adds mā before the verb. These are separate operations.

22. Forming other passive past persons

Passive formation applies to other persons as well as the basic فَعَلَ → فُعِلَ. The person/number suffix stays, while stem vowels become passive.

Word / formMeaning / explanation
ضَرَبْتَ → ضُرِبْتَyou (male) struck → you were struck.
ضَرَبْتِ → ضُرِبْتِyou (female) struck → you were struck.
ضَرَبْتُ → ضُرِبْتُI struck → I was struck.
ضَرَبُوا → ضُرِبُواthey (men) struck → they were struck.
ضَرَبْنَا → ضُرِبْنَاwe struck → we were struck.

For example, ضَرَبْتُ retains its first-person suffix ـتُ in ضُرِبْتُ; the vowel change inside the verb marks the passive.

23. Morphological analysis of the source exercises

The textbook exercises use past verbs from several roots. Each must be understood both for meaning and for its grammatical person and voice.

Word / formMeaning / explanation
كَتَبَhe wrote; third-person masculine singular, affirmative active.
مَنَعَhe prevented; third-person masculine singular, affirmative active.
اِجْتَنَبَhe avoided; third-person masculine singular, affirmative active in a derived stem.
عَلِمَhe knew; third-person masculine singular, affirmative active.
تَرَكَhe left; third-person masculine singular, affirmative active.

These differ in lexical meaning but share grammatical person. Although عَلِمَ has kasrah on its middle consonant, it is still active past; not every active verb has the exact stem pattern فَعَلَ.

24. Reading past forms for their full meaning

To translate an Arabic verb accurately, its lexical root is not enough. Person, number, gender, voice and negation all contribute to its meaning.

Word / formMeaning / explanation
مَا كَتَبُواthose men did not write; third-person masculine plural, negative active.
مَا مَنَعْتُمْyou men did not prevent; second-person masculine plural, negative active.
اِجْتَنَبْتُنَّyou women avoided; second-person feminine plural, affirmative active.
كُتِبَit was written; third-person masculine singular, affirmative passive.

The particle mā marks negation in the first two; ـتُنَّ marks feminine plural address in the third; passive stem vowels determine the fourth.

25. The four governing rules of the paradigm

Four principles organize the full past-tense paradigm:
1. Person and number: six third-person, six second-person and two first-person forms make fourteen.
2. Active: the action is attributed to its doer, as in ضَرَبَ.
3. Passive: the appropriate stem vowels change, as in ضَرَبَ → ضُرِبَ.
4. Negation: mā precedes the affirmative past, as in ضُرِبَ → مَا ضُرِبَ.
For each form, identify who is involved, how many, whether the verb is active or passive, and whether it is affirmative or negative. Together these distinctions explain the full 14 × 4 paradigm.
